So many helpful people, so many great responses - it would feel excessive to try to answer to all of them.
Instead, thanks all of you!
@G-Dog there’s no doubt that I will share my experiences here - I can’t believe it took me so long to get hooked with TB... I’ve read posts in the past now and then, but I only created an account in order to buy a bass here

I will read the comparison that you posted in the wiki - but I think the advice from several others that there really is value in allowing myself to get better and to understand better what I need is very valuable.
As for G.A.S. - I’m a scuba diver and avid underwater photographer - if anyone cares, I have some
pictures up on the web - if you think bass gear is expensive, I invite you to talk to me and some of my photographer friends. I know quite a few people who jump into the water with $20k+ strapped to their chest... Or maybe you want to talk to my daughter about the cost about her 5/4 Bb concert tuba... yeah, my financial advisor is used to bad news

The whole point of asking here is not to give any of you permission to make me buy things, or to get you to convince me to spend money, but to hear from people who know more (let‘s face it, a LOT more) than I do about all of this. And to let that help me make my own decisions.
@ShawnG I doubt I‘ll spend more than $100k on gear. At least not this year.
